A kind of working process of the braking force control system that is applied to Recovering Waste Energy of Braking in Automobiles is as follows:
Gather a pressure sensor 22 by brake controller (BCU) 21 in the braking procedure, No. two pressure sensors 23, No. three pressure sensors 24, No. four pressure sensors 25, No. five pressure sensors 26, No. six pressure sensors 27, No. seven pressure sensors 28, the signal of No. eight pressure sensors 29 and pedal stroke simulator 30, and by entire car controller 21(HCU) obtain the maximum braking force Tm0 that drive motor 19 can produce, brake controller (BCU) 21 is through calculating the braking intention that identifies chaufeur, and obtain antero posterior axis target hydraulic braking force T1, T2 and target motor braking power Tm.Antero posterior axis target hydraulic braking force T1 and T2 are obtained by brake controller (BCU) 21 direct control electromagnetic valve 8-18 and motor Hydraulic Pump 6, target motor braking power Tm sends entire car controller (HCU) 20 to by brake controller (BCU) 21, and is obtained by entire car controller (HCU) 20 controlling and driving motors (M) 19.
When current axis needs supercharging, No. four electromagnetic valves 11 of brake controller (BCU) 21 controls are opened, No. six electromagnetic valve 13 is closed, make the high-voltage oil liquid in the high pressure accumulator enter the front-wheel wheel cylinder, when rear axle needs supercharging, No. five electromagnetic valves 12 of brake controller (BCU) 21 controls are opened, and No. seven electromagnetic valve 14 is closed, and makes the high-voltage oil liquid in the high pressure accumulator enter the trailing wheel wheel cylinder; When current axis needs pressurize, brake controller (BCU) 21 No. four electromagnetic valves 11 of control and No. six electromagnetic valves 13 are closed, and preceding axle pressure remains unchanged, when rear axle needs pressurize, brake controller (BCU) 21 No. five electromagnetic valves 12 of control and No. seven electromagnetic valves 14 are closed, and back axle pressure remains unchanged; When current axis need reduce brake-pressure, No. four electromagnetic valves 11 of brake controller (BCU) 21 controls are closed, No. six electromagnetic valve 13 is opened, braking liquid in the front axle wheel cylinder enters liquid storing cup 3 by No. six electromagnetic valves 13, when rear axle need reduce brake-pressure, No. five electromagnetic valves 12 of brake controller (BCU) 21 controls are closed, and No. seven electromagnetic valve 14 is opened, and the braking liquid in the rear axle wheel cylinder enters fluid cup 3 by No. seven electromagnetic valves 14.
No. eight electromagnetic valves 15 are used for controlling two pressure of wheel braking cylinder of front axle with No. nine electromagnetic valves 16 as the pressure of wheel braking cylinder control cock to be changed with different rate of changes, and No. ten electromagnetic valves 17 are used for realizing that as the pressure of wheel braking cylinder control cock two pressure of wheel braking cylinder of rear axle change with different rate of changes with ride on Bus No. 11 electromagnetic valve 18.For example, current axis two wheel cylinder the near front wheel cylinders 31 need supercharging and simultaneously right front wheel cylinder 32 needs when reducing pressure, and close No. nine electromagnetic valves 16 of off front wheel wheel cylinder 32 earlier, open electromagnetic valve 11 No. four, make 31 superchargings of the near front wheel wheel cylinder; After treating that the near front wheel wheel cylinder 31 pressure change to expected value, No. eight electromagnetic valve 15 is closed, and No. four electromagnetic valve 11 is closed, and No. nine electromagnetic valve 16 is opened, and No. six electromagnetic valve 13 is opened, and makes 32 decompressions of off front wheel wheel cylinder.
For above all braking modes, fluid during its supercharging all comes from high pressure accumulator 5, and when decompression fluid directly flow back to liquid storing cup 3, its supercharging, pressurize and decompression process all with master cylinder in pressure independent, therefore in the braking procedure, the variation of pressure of wheel braking cylinder can not cause the uncomfortable property of driver pedal sensation.
When electric system lost efficacy, all electromagnetic valves and electric-motor pump all are failure to actuate, high pressure oil in the high pressure accumulator can't be given the wheel cylinder supercharging, at this moment chaufeur is stepped on brake pedal 1, fluid in the master cylinder can arrive front axle and rear axle wheel cylinder 31-34 respectively by No. two electromagnetic valves 9 and No. three electromagnetism 10, produces braking force.Therefore this brake equipment still can be realized braking function when electric system loses efficacy, and made car deceleration or parking, satisfied laws and regulations requirement.
When the brake fluid pressure in the high pressure accumulator 5 was lower than low pressure threshold value P1, Hydraulic Pump 6 was started working, and braking liquid is extracted in the high pressure accumulator 5 from liquid storing cup 3, made the brake fluid pressure in the high pressure accumulator 5 remain effective operation pressure; When the brake fluid pressure in the high pressure accumulator 5 is higher than high-pressure door limit value P2, braking liquid in the high pressure accumulator 5 can be opened by pass valve 4, enters in the liquid storing cup 3, thus the brake fluid pressure in the reduction high pressure accumulator 5, avoid hypertonia, and damage high pressure accumulator 5.
The brake energy recovering system scheme that the present invention proposes can obtain the brake pedal feel identical with traditional vehicle, this be because:
The brake system scheme that the present invention proposes is in braking procedure, and No. two electromagnetic valves 9 and No. three electromagnetic valves 10 are closed, and has cut off being connected between master cylinder and the wheel cylinder, and promptly to change be independence separately to the pressure of master cylinder and wheel cylinder, is independent of each other; And form the brake pedal feel that simulator 7 can drive simulating person, electromagnetic valve 8 of glancing impact is opened, braking liquid in the master cylinder 2 enters in the stroke simulator 7 through an electromagnetic valve 8, stroke simulator applies counter-force, drive simulating person's pedal sense, when loosen the brake, braking liquid flows back to the master cylinder 2 through an electromagnetic valve 8 from stroke simulator 7, makes driver pedal feel comfortable.
By above explanation as can be seen, braking liquid by No. seven electromagnetic valves 14 of No. four electromagnetic valve 11-has only a flow direction, and two flow directions are arranged by the braking liquid of No. three electromagnetic valves 10 of an electromagnetic valve 8-and No. eight electromagnetic valve 15-ride on Bus No. 11 electromagnetic valves 18, therefore in the electromagnetic valve among Fig. 1, arrow on No. seven electromagnetic valve 14 icons of No. two electromagnetic valve 9-is a unidirectional arrow, and the arrow on electromagnetic valve 8 and No. eight electromagnetic valve 15-ride on Bus No. 11 electromagnetic valve 18 icons is a four-headed arrow.
The various embodiments described above only are used to illustrate the present invention, the structure of each parts wherein, and connection modes etc. all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement all should not got rid of outside protection scope of the present invention.
